Fl f 45.Ar program ... 46.Sh DESCRIPTION 47The 48.Nm 49utility checks the standard binary, manual page, and source 50directories for the specified programs, printing out the paths of any 51it finds. 52The supplied program names are first stripped of leading 53path name components, any single trailing extension added by 54.Xr gzip 1 , 55.Xr compress 1 , 56or 57.Xr bzip2 1 , 58and the leading 59.Ql s.\& 60or trailing 61.Ql ,v 62from a source code control system. 63.Pp 64The default path searched is the string returned by the 65.Xr sysctl 8 66utility for the 67.Va user.cs_path 68string, with 69.Pa /usr/libexec , 70.Pa /usr/games 71and the current user's 72.Ev $PATH 73appended. 74Manual pages are searched by default along the 75.Ev $MANPATH . 76Program sources are located in a list of known standard places, 77including all the subdirectories of 78.Pa /usr/src 79and 80.Pa /usr/pkgsrc . 81.Pp 82The following options are available: 83.Bl -tag -width indent 84.It Fl B 85Specify directories to search for binaries. 86Requires the 87.Fl f 88option. 89.It Fl M 90Specify directories to search for manual pages. 91Requires the 92.Fl f 93option. 94.It Fl S 95Specify directories to search for program sources. Requires the 96.Fl f 97option. 98.It Fl a 99Report all matches instead of only the first of each requested type. 100.It Fl b 101Search for binaries. 102.It Fl f 103Delimits the list of directories after the 104.Fl B , 105.Fl M , 106or 107.Fl S 108options, and indicates the beginning of the 109.Ar program 110list. 111.It Fl m 112Search for manual pages. 113.It Fl q 114.Pq Dq quiet . 115Suppress the output of the utility name in front of the normal 116output line. 117This can become handy for use in a backquote substitution of a 118shell command line, see 119.Sx EXAMPLES . 120.It Fl s 121Search for source directories. 122.It Fl u 123Search for 124.Dq unusual 125entries. 126A file is said to be unusual if it does not have at least 127one entry of each requested type. 128Only the name of the unusual entry is printed. 129.It Fl x 130Do not use 131.Dq expensive 132tools when searching for source directories. 133Normally, after unsuccessfully searching all the first-level 134subdirectories of the source directory list, 135.Nm 136will ask 137.Xr locate 1 138to find the entry on its behalf. 139Since this can take much longer, it can be turned off with 140.Fl x . 141.El 142.Sh EXAMPLES 143The following finds all utilities under 144.Pa /usr/bin 145that do not have documentation: 146.Pp 147.Dl whereis -m -u /usr/bin/* 148.Pp 149Change to the source code directory of 150.Xr ls 1 : 151.Pp 152.Dl cd `whereis -sq ls` 153.Sh SEE ALSO 154.Xr find 1 , 155.Xr locate 1 , 156.Xr man 1 , 157.Xr which 1 , 158.Xr sysctl 8 159.Sh HISTORY 160The 161.Nm 162utility appeared in 163.Bx 3.0 . 164This version re-implements the historical 165functionality that was lost in 166.Bx 4.4 . 167.Sh AUTHORS 168This implementation of the 169.Nm 170command was written by 171.An J\(:org Wunsch . 172.Sh BUGS 173This re-implementation of the 174.Nm 175utility is not bug-for-bug compatible with historical versions. 176It is believed to be compatible with the version that was shipping with 177.Fx 2.2 178through 179.Fx 4.5 180though. 181.Pp 182The 183.Nm 184utility can report some unrelated source entries when the 185.Fl a 186option is specified. 187
